Is this from a clogged duct? Pic

Woke up with a full breast. Pumped 4 oz from my right breast which is the most I've ever been able to pump at one time. Noticed the bottom of my breast had a painful knot, sore to the touch. Then on the side I have these red streaks. Is it just a clogged duct? I'd have a fever if it was mastitis right?
